# Basic configuration

- ec2_asg:
    name: special
    load_balancers: [ 'lb1', 'lb2' ]
    availability_zones: [ 'eu-west-1a', 'eu-west-1b' ]
    launch_config_name: 'lc-1'
    min_size: 1
    max_size: 10
    desired_capacity: 5
    vpc_zone_identifier: [ 'subnet-abcd1234', 'subnet-1a2b3c4d' ]
    tags:
      - environment: production
        propagate_at_launch: no

# Rolling ASG Updates

Below is an example of how to assign a new launch config to an ASG and terminate old instances.

All instances in "myasg" that do not have the launch configuration named "my_new_lc" will be terminated in
a rolling fashion with instances using the current launch configuration, "my_new_lc".

This could also be considered a rolling deploy of a pre-baked AMI.

If this is a newly created group, the instances will not be replaced since all instances
will have the current launch configuration.

- name: create launch config
  ec2_lc:
    name: my_new_lc
    image_id: ami-lkajsf
    key_name: mykey
    region: us-east-1
    security_groups: sg-23423
    instance_type: m1.small
    assign_public_ip: yes

- ec2_asg:
    name: myasg
    launch_config_name: my_new_lc
    health_check_period: 60
    health_check_type: ELB
    replace_all_instances: yes
    min_size: 5
    max_size: 5
    desired_capacity: 5
    region: us-east-1

To only replace a couple of instances instead of all of them, supply a list
to "replace_instances":

- ec2_asg:
    name: myasg
    launch_config_name: my_new_lc
    health_check_period: 60
    health_check_type: ELB
    replace_instances:
    - i-b345231
    - i-24c2931
    min_size: 5
    max_size: 5
    desired_capacity: 5
    region: us-east-1
